Part 2/5:
The issue arose when Crowdstrike pushed an update to the Falcon software, which contained a maliciously formed Kernel-mode driver. This update, which was intended to enhance the security capabilities of the Falcon product, instead triggered a catastrophic failure across the world.
The root cause of the problem was a null pointer dereference within the Falcon driver. When the corrupted update file was loaded, the driver attempted to access a null pointer, causing the system to crash. This issue was exacerbated by the fact that the Falcon driver is a boot-start driver, meaning it is essential for the system to boot up properly.
